Application filed Ju1y'27,

' To all w from c't may concern:

Be it known that we, 'Eoioro DELTA, a subject of the King of Italy, and VINCENT oiinano, a citizen of the United States, both residing at New York city, borough'of Manhattan. in they county and State of New York, have invented a certain new and useful Improved Fan *for Sewing Machines, of which the ii'ollowingis a specification.

This invention relates tofans adapted to be associated with a sewing machine fly wheel in such manner that during the operation of the machine, the fan will supply air the hand,

in motion to the operator, thereby rendering her activities more comfortable and less irksome in hot weather.

It has been heretofore suggested to associate a fan with asewing machine, but in the prior constructions the fan has either. been entirely without protection. or provided with a guard supported on, the base of table of the machine. As the fan is usually positioned directly adjacent the fly wheel, to

which the operator, in hand operated machines, finds occasion to frequently apply such fans, unless properly protected or guarded are a menace to the operators hands, and, accordingly, in the majority of cases have been covered with a suitable guard. In every instance, so far as we are aware, these guards have been sup ported upon the table of the machine in such manner that they unduly encumber the table and are large, cumbersome and unsightly. Moreover, in many instances, the

guard does not fulfill its function in that it doesnot properly protect the hands of the operator against engagement with the operating parts.

The object of the present invention is to provide fans of the general character specilied adapted to'be associated with the fly wheel of a sewing machine in. a compact and uncumbersome manner, andso (1011-. structed that the guard of the fan will be carried by the fan in a compact manner, leaving the table entirely unencumbered, while fully protecting the hands of the operator against danger from'the blades of the fan.

Features of the invention, other than those. specified, will be apparent from the hereinafter detailed description and claim, when Flgure 1.

but the-construction therein shown is'to be understood as illustrative, only, and not as defining the limits of the invention.

Figure 1 illustrates theend of a sewing machine, showing a fan embodying the present invention associated therewith; and, Figure 2 is a perspective view of the fan of this invention.

Referring to the drawings, 1 designates the frame of the machine, provided with the usual fly wheel 2, adjacent which is positioned the customary pulley 3 I a belt, not shown, cooperates in the driving of" the machine. The fly wheel 2 or pulley with which 3 is usually provided with a hub 4 which projects beyond the pulley 3 as shown in tion, the fan is adapted to ice-secured to this hub.

The fan which is shown in perspective in In accordance with this inven- Figure 2 embodies a hub 5 from which radiw ate a plurality of blades 6 secured tothe hub of said fan in any suitable manner. The

In order to protect the hands of the operator against engaging with the blades Sand being hurtor injured thereby, an annular ring 9 is positioned peripherally ofthe fan and secured to the outer ends of the blades, so that the blades are housed within the ring 9 which is of a width at least equal to the If desired, the inner face-of the ring may be covered with a wire mesh provided with an aperture through which the hub 4 of the fly wheel may be passed, so as to preclude the hands from being slipped in from the thickness of the fan as shown in Figure- 1.

i add to the length of side of the fan, but, in practice, we find that this, is not essential. Moreover, both faces of the fan may be covered with a Wire mesh to preclude the fabric from being sucked into the fan by the suction produced by the blades thereof, during the rapid revolving of the 'fan.

It Will be apparent from the scription, that We have produced a fan for sewing machines, which is entirely self contained and serves, in itself, as r a guard against accident or injury to the hands of an operator. The guard in no Wise encumbers the table of the machine and is of such compact nature that it does not materially the machine. In'practice, the thickness through the fan may be even less than that shown in the drawings, so that minimum space is taken up by the fan, in contii'adistinction to the relatively great space occupied by the guards of previous constructions.
